The combination PHY is SATA (Serial ATA) compliant with SATA 3.0 Specification, PCIe (Peripheral Component Interconnect Express) compliant with PIPE interface protocol, and USB (USB 3.0, USB 2.0) compliant (USB High-speed and Full speed). Supporting additional internal power gating, reference clock control, and PLL control helps reduce power consumption. The PHY is also very helpful for a range of situations under varied considerations of power consumption because of the adaptability of the aforementioned low power mode choice.
